Hello Jakob,

Lexemes are not implemented as part of Wikibase itself but in a Wikibase extension [1] because not all Wikibase users are interested in storing lexical data. The data model "formal" description is here [2] and the full RDF document is here [3].

I have added a link to the Lexeme data model from the Wikibase data model page.

Cheers,

Thomas

Hi,

I just noted that the official description of the Wikibase data model at

https://www.mediawiki.org/wiki/Wikibase/DataModel

and the description of JSON serialization lack a description of Lexemes, Forms, and Senses. The documentation of Wikibase RDF has been updated but the underlying data model description seems outdated.

At least JSON specification is part of Wikibase source code:

A more formal document (e.g. JSON Schema) may help to detect when implementation and documentatation get out of sync.

One way to generate a JSON schema would be to use Wikidata-Toolkit's implementation, which can generate a JSON schema via Jackson. It could be used to validate the entire data model.
